To ALL' WHOM 1r MAY CONCERN;

Be it'iknoivn that L1 PAPIN, of SLLouis, in the countyof St. Lot ligand State (if-Missouri, have made certain new and useful Improvenents in Appar'atiis for Stamping and Mining Purposes and I do hereby declare that thefollowing is a full and clear description thereof, reference being hall to the accompanying drawings, 'ai'id to the letters of refer'en'ce marked thereon.

having for their. object the sanle, nltimate-result, viz, the extrfactioufroni injnes and'redu'ction ofores.; In brief,

, the apparatus consists of a series of v ertical staiiips, surrounding and operatedbye horizontal druin', the top face of which has a serrated railing, forming a seriesof inclined planes, which elevate and then let drop the stan ps as Ithedrurn'ivolves, the said stamps beintg elevated by means of pins or sheaves attached thereto, slidr'rollin'g ipion the aforesaid revolving serrated railing. I

.lliisiapparatusis intendedforlthe general mining purposes of sinall operatorg-and r elatestoseveral devices,

The-particular features of .the ini'ention'relate, firstly, to a device for-producing anfadjustable stroke of' the stamp; secondly, to the co mbinution' of a revolting or drill-stamp.with a fixed. or sitnply vertical stroke stamp, arrangedfin the sanie stampboi'lj thirdly, to the'eonstructiop and arrangement of the drill-stamp,'w' hich may be operatedeitheiautomatically or byhand; fourthly,to the construction and arrangement of the-stamping'-' box in. tv ro compartments, the door of one of whichshall'be higher than that of the othf'pfifthly, to africtionbrake, for, regulating the force oftho blo'vr given'by the eta np; .and sixthlflto the peculiar eonstructionof the driving-drum, which adapts it to .thepropulsion of'the minin'gfpumps' or lifts.-

To enable those-skilled in the art to nia'ke and se my improved [pining-apparatus, I vill proceed to describe.

its construction and operation. v I

Fignrel'of the drawings is a central sectional elevation. Figure 2 is a general plan.v Figure 3is a side elevation-ofthe'efrictiori bralte for eta mp. v

Figure 4 is a top vi'ewof stamp-shoe, showing the radial corrugations acted 'upon' by the spri'ng-pawbto turn the stamp. i I

Figure 5 is an enlarged sectional elevation'ofstarnp box, taken. 'on'the line a: y of fig. 2. my; actuating-drum Ais erected upon a vertical driving-shaft, A. On top of .this drum .is a series" of inclined railings, a, surrounding :the drun near its periphery,- and forming a kind of serrated riin, which, as it revolves, passes successively under each of the pins or sheaves b, that project from the inner sides .of the stamping-rodsB or B, and in this, manner the stamps are raised, much in the same manner that they are in the Murray machine, patented in 1859 I I I The drum A may operate any'desirednumher of stamps'B B, the said stamps being arranged aroundthe periphery of the drum, and just closeenough to-it to be operated by. the'railing o'r earns a. The pins or sheaves b', which are attached to the stamping-rodslor the purpose of-elevatingthem, are rendered adjustable as toheight by-means of the set-screws, b, whieh are made to enter'grcoves cut'in the stainp-r ods at different heights,

as shown in figJ. 'In this manner the'said-sheaves b'inay be adjusted to any height, and the rod still permitted to revolve, as hereinafter explained. The objectof this adjustable arrangement of the. sheave is to cause the stamp to' -strike a blow more or less severe, as may be required.

. It is fpund that in the ordinary stamping-mills, a portion of the mineral rem'ains untouched by'the stamps, owing-to its being forced up at the sides of the stamps. lo overcome this difiiculty, -I use two stamps, B and 33in battery in the same stamping-boar, the stamp B being a round one, and made to revolve like a drill, while the stat 11p B isimade square, and operated in afixed position; .The ore 'is to befirst placed tinder the revolving stamp B, which, by its combined revolving andvertical stroke, will have access to every-portion of the unbroken ore,'an d thoroughly crack and break up the large pieces, which will then be passed under the square stamp,-

that will then be able to thoroughly pulverize the partially-broken ore.

The shoe, Bflof thereiiolving st'amp,-has'its top end provided ivith radial serrations, as-is' clearly shown in" E38. 1 and 4. The spiing-pawi d, attached to the framework D, will -engng'e one of these serrations at each upward stroke of the stamp, and turn it aronnda little like a stone-drill, the striking 'orlower face of the stein p-shoe B being arranged with cozfr ngetions or crossor.ster shapedi'aised. ridges; then,- owing vto said-'tnrning of the st'a mp, the snidridges of snldstrikingfnce will be permitted. to strike new matei ial at each stroke,

thereby thorong hly breaking npnil ofthe lni'ge pieces- 4 1 r Thedrili-stamp may be turned around by mean s ofn'bar 0; level, withonttheaid ot' the pawl d.

:The floor of the stamping-box should he-inade, say, two 91 three inehes (inure tor-less) higher than the floor of the box E, and the two boxes separated by the pdrtition 6,-5.5 shown in fig; 5. The dim-stamp will operate inthe higher box, from which it will beqdite ensj to pass the partiaily-broken-ore downinto the finishing: box, E, by raising the dividing-onrtition-e,\nm1 from-thediist' ho'; E,- the pnivcrized'ore willbe disc hnrged tizu-ongh the gate, 0', intotheccntr'ol trough F,"whei'e it willbe further redn'ced by the arnstms G, which ore to be drawn around over the mess of broken eye by thechnins g, attached to the nr 'ns A, projecting from'the driving-shaft: The trongh F may he need niso for ainnlgamatingrpnrposea In order to regulate the force of the biow given by the stamps, I apply a fri tion-brake, H, which consists t of est nail roliei nt rnnged to pie ss against the eideof the stamp-yogi, nndodever nri nnged to press the said roiier np e'goinst the'snid rofd more cr 1ess sev erely, as byfpressing on thelever'with the hand 'of -theoperntw, or, n ofe-peimenently, by the npplicationofi a, weight iappliedcto the lever, which weight niay' he movedont towardthe :end of lever, ns may be desired.

Attdched to the bottom side of the'di'um A is a. sex ies of verti'cei ni-ms',a' ,nround; which a. belt ,-I, iney he placed, so its to. aietunte' a eounter'wheel, I, the latter wheel he ing"used to" drive thej'pnmping or iiftinginechinery ofthe mine. I I I R "To prevent the roller 6 min moving 0d the track a when, the drill=etnn p.B-is turned, I guide said roller by the pi'ojeetion b on the sleeve 6 running'in the slot formed the guide-plate I) end the fmme-piece.D.

' Having described my invention, what I'cluim,-is- V 1. The statnp B, its eer ated shoe BF, and the spiing-pawl 41, when a rangedend' operetcd as herein described and eet forth; I 2. Thei etaznping-bogesEE', when constructed with the floor of one higher than that. of the other, and

' 'a ri'anged as herein .deecrihe'dhnd shown.

3. The friction-brake H, when applied to the rod B or B, as aind for the purpose set foi-th.
